+# Display All The Terminal Colors
+
+The following snippet of bash scripting will print out a nicely formatted
+collection of all the terminal colors.
+
+```bash
+for x in {0..8}; do 
+    for i in {30..37}; do 
+        for a in {40..47}; do 
+            echo -ne "\e[$x;$i;$a""m\\\e[$x;$i;$a""m\e[0;37;40m "
+        done
+        echo
+    done
+done
+echo ""
+```
+
+This is a great way to figure out the escape codes you need for coloring and
+styling text in a bash script.
